Title: Narayan Raman: Innovator in Aqueous Copolymer Dispersions
Introduction
Narayan Raman is a notable inventor based in Cincinnati, OH (US). He has made significant contributions to the field of polymer chemistry, particularly in the development of aqueous copolymer dispersions. His innovative work has led to the creation of a patented technology that enhances coating compositions.
Latest Patents
Narayan Raman holds a patent for "Aqueous copolymer dispersions and their use in coating compositions." This invention involves a multi-stage emulsion polymerization process. The first stage polymerizes a monomer composition that includes at least 88 wt % of a vinyl ester of a Cto Ccarboxylic acid and up to 12 wt % ethylene. The second stage involves polymerizing a second monomer composition in the presence of the first stage polymer. This innovative approach results in a second stage polymer with a glass transition temperature (Tg) of ≤20° C. The process is conducted with a stabilizing system that includes protective colloids and ionic surfactants.
